Automatic VMDK Optimization When System Uptime is Priority #1

Maintaining High Availability and Performance in a Virtualized Environment

Maintaining High Availability & Performance in a Virtualized EnvironmentNSC’s database, web and application servers are virtualized and distributed across multiple datacenters for performance and reliability considerations. They use both direct attached and SAN storage. NSC noticed that during busy periods there was an increase in demand for memory and performance declined. Upon investigation they realized this was attributable to free space fragmentation on their virtual disks.

“PerfectDisk vSphere can’t be beat for reliability, speed and effectiveness.” 

- Brandon Smith, IT Manager, NSC

NSC experienced situations where severe disk fragmentation caused heavily loaded systems to become so far behind in processing the disk queue that they were rendered unusable. In addition to the journal and log file fragmentation, NSC also noticed that their databases became logically fragmented when they could not grow contiguously. This combination led NSC to seek a solution that would help it maintain its performance objectives.
